Abstract
The invention proposes a goods-storage rack having supports (5), which extend between crossmembers, are supported on the latter, are designed in the form of downwardly open profiles and are each made up of a first side wall (11) on the one side of a vertical profile centre plane (M), a second side wall (12) on the other side of the vertical profile centre plane (M) and a horizontal wall (10), which connects the side walls (11, 12) and the upper side of which forms the goods support (10A). For the purpose of fastening the respective support (5), the crossmember has two slots (21, 22), which each have a latching protrusion which, in the latched state, engages with a form fit in an opening (4) in the respective side wall (11, 12), wherein the openings (4) are each located in end portions (15) of the side walls (11, 12), which are short in comparison with centre portions (16), which form the predominant part of the length of the side walls (11, 12). In order to create a goods-storage rack which is easier to assemble than rack systems with a comparable load, the end portions (15) are separated from the centre portions (16) in each case by a slot (33) which, starting from the lower edge (34) of the side wall (11, 12), extends only over part of the height of the side wall (11, 12). In comparison with the course followed by the wall of the centre portion (16), the course followed by the wall of the end portions (15) in the direction of the lower edge (34) of the latter is offset in the direction of the profile centre plane.
Description
Goods storage rack The invention relates to a goods storage rack according to the preamble of patent claim 1.
Components of such a rack are two cross-beams which are arranged parallel with each other and supports which extend between the cross-beams and which are supported thereon. The supports are in the form of profiles which are open in a downward direction and are composed in each case of a first side wall at one side of a vertical profile center plane and a second side wall at the other side of a vertical profile center plane and a hori-zontal wall which connects the side walls. The upper side of the horizontal wall forms the goods support. The cross-beam has a cross-beam upper side, a cross-beam rear wall and, in order to secure the respective support, two slots which extend from the cross-beam upper side up to the cross-beam rear wall and which at that location have a locking projection which in the locking state engages in a positive-locking manner in an opening in the respec-tive side wall. The openings are located in each case in end portions of the side walls.
These end portions are short in comparison with the central portions which form the largest portion of the length of the side walls.
Such a rack is known from DE 10 2010 038 968 Al and is used mainly in large rack ware-houses having autonomously controlled storage and removal of unit goods. The unit goods are, for example, boxes or standardized containers, such as, for example, small containers.
In order to store unit goods, the rack is subdivided into a large number of support faces which are arranged one above the other and beside each other, wherein the supports with the elongate support faces have such a depth that a plurality of unit goods can also be stored in a state staggered one behind the other in each compartment. In order to enable a displacement of the unit goods into and out of the rack during storage and removal, a sup-port which extends in the direction of the rack depth, which is without steps as far as pos-sible and which is also referred to as a depth support is required.
In most cases, the supports are mounted in pairs, wherein they are supported in each case with one end thereof on a front cross-beam and with the other end thereof on a rear cross-beam. The fixing is carried out by means of locking. To this end, the supports are pressed together at the side walls thereof and at the same time under considerable pressure pressed from above into the slots of the cross-beam. To this end, considerable forces are required since the profile which forms the support is relatively stable in terms of deformation and is additionally reinforced by means of folds by means of which the profile is reinforced Date Recue/Date Received 2023-02-22

- 2 -along the lower edges thereof. Since considerable forces have to be applied for the defor-mation and assembly of the support, the assembly complexity with the rack according to DE 10 2010 038 968 Al is high on the whole.
A rack for storage and picking purposes according to EP 0 882 660 B1 is composed of a system of vertical pillars to which horizontal cross-beams are secured in accordance with the individual compartment heights. The cross-beams are also in this instance configured to provide grip for supports which extend through the depth of the rack. The supports are constructed in such a manner that they provide a support face for two mutually adjacent load carriers, wherein they additionally provide a longitudinal guide in the rack for them so that contact of adjacent load carriers is excluded. In order to be able to provide both a support face for two load carriers and to separate them from each other, the support is constructed with two parallel goods supports. On the support a chamfer which is orientated relative to the cross-beam is formed at the ends of the goods supports in order to reduce the resistance for the unit goods when moving from the cross-beam to the goods support.
The entire support is in one piece and can be engaged on the cross-beam.
Another generic rack for goods storage is described in WO 2010/022448 Al.
An object of the invention is to provide a rack for goods storage in which the assembly complexity is less in comparison with rack systems having a comparable load-bearing ca-pacity.
In order to achieve this objective, in a rack for goods storage having the features set out in the introduction it is proposed that the end portions of the side walls are each separated from the central portions by means of a slot which extends, from the lower edge of the side wall, over only a portion of the height of the side wall and that the end portions have in the direction toward the lower edge thereof a wall extent which in comparison with the wall extent on the central portion is offset in the direction toward the profile center plane.
The rack according to the invention is characterized in that it requires little assembly effort.
The fixing of the supports is carried out by means of simple clip-fitting. On the one hand, the slots on the cross-beam and, on the other hand, the end portions, which engage in the slots, of the side walls of the supports are used for this. The support can be locked to the cross-beam with little application of force. Generally, a slight pressure from above onto the respective end of the support will already be sufficient to engage and thereby to lock this end of the support to the respective cross-beam in a secure and durable manner.

- 3 -additional pressing together of the two side walls so that they are bent toward each other is not required. Instead, as a result of the configuration of the end portions of the two side walls, simply applying pressure from above to the support will already be sufficient to en-gage the respective end of the support with the respective cross-beam in a secure and durable manner.
Securing steps such as screwing the components to each other or fitting rivets are not required so that significantly reduced assembly times are achieved. When the rack is as-sembled, it is sufficient to install a movable lifting platform in front of the rack in order to then enable fitters to place all goods supports from the lifting platform in the rack and to engage them not only with the cross-beam at the rack front side, but also at the other, rear cross-beam by simply pressing down vertically, and thus to fix them. An additional pressing-together of the two side walls of the support is not necessary in this instance. In addition, as a result of the engagement which can be clearly heard, it is ensured that the fixing is achieved in a reliable manner, and the assembly has not been carried out, for instance, in an intermediate stage.
The slots which extend from the cross-beam upper side into the cross-beam rear wall are arranged in pairs, wherein the slots taper in a slightly conical manner on the cross-beam rear wall. At mid-height of the slots, locking projections are formed in the slots, wherein the locking projections are formed in the direction toward each other in each case. If the re-spective end portion is now lowered from above into the respective slot, the configuration of the slot and the locking projections ensures that the end portions are resiliently pressed together. From a specific lowering into the slots, the support is then positioned in such a manner with respect to the cross-beam that the locking projections engage in the openings formed on the end portions. The end portion which was previously bent resiliently inward relaxes, whereby a permanent positive-locking connection is produced between the locking element and the opening.
The locking projections on the cross-beam and the openings on the support are constructed in such a manner with respect to each other that the goods support and the surface of the cross-beam upper side are located at the same vertical level and are in alignment with each other. Consequently, a displacement of the unit goods on the support is enabled without becoming jammed or caught.

- 4 -For an assembly with little application of force, the vertical slot between the end portion and the central portion is advantageous. This slot leads to a particularly easy deformability of the end portion during assembly.
The supports can be produced as different structural types. With a first structural type, the support which is in the form of a profile is configured in the same manner in each case at the two end regions thereof. Such a support serves to store and remove goods both from one side of the rack and from the other side of the rack. In this instance, push-through protection means are advantageous, for example, in the center of the length of the goods supports. In order to secure the push-through protection means, a securing structure may be formed on the hori-zontal wall of the support, for example, an opening in the horizontal wall for inserting the push-through protection means therein.
In the case of a second structural type of the support, it is configured differently at both end regions thereof. The goods storage is carried out only from one rack side. At the other rack side, stops or stop elements which are arranged at that location may ensure that goods or bundles of goods only reach this location and go no further.
In the case of a third structural type of the support, it is provided along the horizontal face thereof which acts as a goods support with an upwardly projecting edge in the form of a rib which also extends over the entire length of the support. The edge serves to position the stored goods in a lateral direction and to prevent sliding of the goods.
In order to enable the clip-fitting of the support to the cross-beam by applying only little vertical pressure, it is advantageous for the wall extent on the end portions to be increas-ingly offset further in a downward direction in the direction toward the profile center plane, for example, in individual steps.
It is not necessary for the end portion of the side wall to be resiliently deformed over the entire height thereof to the same extent. It is therefore proposed that the end portions be composed of two regions. The upper region of each end portion forms a wall portion which is arranged at right-angles with respect to the horizontal wall and which is in alignment with the central portion of the side wall. In contrast, the lower region of the end portion is formed by the wall extent which is offset in an inward direction, that is to say, toward the profile center plane.

In contrast, the lower region of the end portion is formed by the wall extent which is offset in an inward direction, that is to say, toward the profile center plane.

- 5 -An important aspect for the low-resistance resilient and reversible deformation is the slot which is provided in the side wall. It is proposed that the slot extends as far as the height of the wall portion which is in alignment with the central portion and which forms the upper region of the end portion of the side wall. In this manner, at least via the height of the slot, a high degree of resilient deformability is achieved, including a complete resilient recovery behavior.
Another significant aspect is an advantageous positioning of the openings which are pro-vided in the two end portions of the side wall. To this end, it is proposed that the opening at least for the most part thereof is located in the wall extent which is offset in the direction toward the profile center plane and extend upward into the wall portion which is in alignment with the central portion of the side wall.
With regard to the configuration of the wall extent which is offset in the direction toward the profile center plane, it is proposed that it is composed in a step-like manner from a sequence of wall portions which are arranged one above the other and which merge into each other along folding or bending lines. They may, for example, be three wall portions which are arranged one above the other, wherein the upper wall portion preferably extends in an oblique manner and also the lowest wall portion. The central wall portion which is arranged therebetween preferably extends perpendicularly or substantially perpendicularly.
It is further proposed that the opening which is used for engagement extends at least over the entire height of the uppermost wall portion of the wall portions which are arranged one above the other.
The supports which are described in this instance are, for example, mounted in a high rack store in significant unit numbers. The compact transport of the supports to the place of use is correspondingly important. In this instance, it has been found to be advantageous to be able to place two supports one inside the other in each case in such a manner that the profile openings thereof face each other. So that this is carried out with minimal volume, it is proposed that, on the end portion, the lower edge, starting from the vertical slot, initially extends horizontally and then so as to rise toward the end thereof. This partial chamfering of the lower edge corresponds to a chamfer with which the upper side of the support is provided at the end thereof. The corresponding configurations enable a space-saving nest-ing arrangement of two supports for the purposes of transport.

Another significant aspect is an advantageous positioning of the openings which are pro-vided in the two end portions of the side wall. To this end, it is proposed that the opening at least for the most part thereof is located in the wall extent which is offset in the direction toward the profile center plane and extend upward into the wall portion which is in alignment with the central portion of the side wall.
With regard to the configuration of the wall extent which is offset in the direction toward the profile center plane, it is proposed that it is composed in a step-like manner from a sequence of wall portions which are arranged one above the other and which merge into each other along folding or bending lines. They may, for example, be three wall portions which are arranged one above the other, wherein the upper wall portion preferably extends in an oblique manner and also the lowest wall portion. The central wall portion which is arranged therebetween preferably extends perpendicularly or substantially perpendicularly.
It is further proposed that the opening which is used for engagement extends at least over the entire height of the uppermost wall portion of the wall portions which are arranged one above the other.
The supports which are described in this instance are, for example, mounted in a high rack store in significant unit numbers. The compact transport of the supports to the place of use is correspondingly important. In this instance, it has been found to be advantageous to be able to place two supports one inside the other in each case in such a manner that the profile openings thereof face each other. So that this is carried out with minimal volume, it is proposed that, on the end portion, the lower edge, starting from the vertical slot, initially extends horizontally and then so as to rise toward the end thereof. This partial chamfering of the lower edge corresponds to a chamfer with which the upper side of the support is provided at the end thereof. The corresponding configurations enable a space-saving nest-ing arrangement of two supports for the purposes of transport.

- 6 -It is further proposed that the horizontal wall of the support merges at the end thereof facing the cross-beam into a declining chamfer.
With one configuration of the cross-beam, it is proposed that the cross-beam upper side is composed of a horizontal face and an oblique face which is adjacent in the direction toward the cross-beam rear wall. Together with a corresponding configuration of the support, it is consequently possible for the chamfer which is formed on the support to meet the oblique face of the cross-beam upper side at an angle between 200 and 60 and preferably at an angle of approximately 350. Consequently, both chamfers together form at the upper side thereof a flat V-shape. This prevents any type of tilting of the goods when displaced in the longitudinal direction of the goods support.
It is further proposed that the side walls of the support in the longitudinal direction of the support are composed of the end portion, the central portion which follows the vertical slot and another end portion at the other end of the support.
For increased capacity for resistance of the support with respect to bending loads as a result of the stored goods, it may be advantageous for the side wall on the central portion to have a greater height than on the end portion or for the side wall on the central portion to have a greater height than on the end portion and on the additional end portion at the other end of the support.
With regard to the slots which are formed in pairs on the cross-beam, it is proposed that the locking projections of the two slots are orientated toward each other. In this instance, it is additionally advantageous for there to be formed for supporting the support on the cross-beam on each locking projection a support face which is directed toward the upper side of the cross-beam and on which the edge of the respective opening is supported.
Purely as a result of this measure, the load forces which are brought about by the stored goods are discharged by the support vertically on the cross-beam. A further vertical support of the support on the cross-beam is not necessary and therefore preferably also not provided.
Preferably, the cross-beam rear wall in order to form the slots is provided with punched-out portions which define the contours of the two locking projections. The portions of these contours facing each other are chamfers the largest spacing of which with respect to each other is greater than the spacing which the lower edges of the end portions have with re-spect to each other.

It is further proposed that the side walls of the support in the longitudinal direction of the support are composed of the end portion, the central portion which follows the vertical slot and another end portion at the other end of the support.
For increased capacity for resistance of the support with respect to bending loads as a result of the stored goods, it may be advantageous for the side wall on the central portion to have a greater height than on the end portion or for the side wall on the central portion to have a greater height than on the end portion and on the additional end portion at the other end of the support.
With regard to the slots which are formed in pairs on the cross-beam, it is proposed that the locking projections of the two slots are orientated toward each other. In this instance, it is additionally advantageous for there to be formed for supporting the support on the cross-beam on each locking projection a support face which is directed toward the upper side of the cross-beam and on which the edge of the respective opening is supported.
Purely as a result of this measure, the load forces which are brought about by the stored goods are discharged by the support vertically on the cross-beam. A further vertical support of the support on the cross-beam is not necessary and therefore preferably also not provided.

With one configuration of the cross-beam, it is proposed that it has a cross-beam front side which faces away from the cross-beam rear wall and which is integral with a wheel guide in the form of a channel-like rail. The wheel guide comprises in cross section a U-shaped profile having a horizontal portion and two portions which are adjacent thereto in a vertically upward direction, wherein the inner vertical portion is at the same time the cross-beam front side. The wheel guide is configured to receive at least one running wheel of a rack operating device, wherein it can roll along the wheel guide and is retained in the track by the vertical portions.
Preferably, the wheel guide is integral with the cross-beam and comprises the wheel guide, the cross-beam front wall and rear wall and the cross-beam upper side.
According to one variant, the support may have an edge which protrudes over the horizontal goods support and which extends longitudinally with respect to the goods support over the entire length of the support.
In order, in addition to reducing the assembly complexity, to also reduce the costs, both the cross-beams with the wheel guide and the supports are constructed in each case integrally, preferably from a bent and punched metal sheet. The metal sheet is cut out or punched out in a corresponding shape and subsequently formed by means of bending processes in such a manner that at the end of the processes the cross-beams and supports are obtained.
In the locking state, a lower edge of the support extends obliquely inward and in a downward direction. The lower edge is formed obliquely relative to the otherwise vertically extending side wall. The objective of the lower edge on the central portion is to reinforce it and to increase the load-bearing capacity.
In particular, the objective of the wall extents which are increasingly offset in the direction toward the profile center plane at the end portions is to enable simple introduction into the cross-beam slots so that a secure and clearly audible engagement of the support in the cross-beam is ensured. As a result of the stepped projection of the wall extents relative to the profile center plane, the wall portions first slide on the outer sides of the slots and sub-sequently along the locking projections.

In particular, this wall extent is step-like or terrace-like in that it is configured to be increasingly offset downward in the direction toward the profile center plane M.
The wall extent which is increasingly offset in a downward direction is composed of an upper oblique wall portion 15a, a central wall portion 15b and a lower oblique wall portion 15c which at the same time forms the lower edge 34 of the support profile.
Preferably, the central wall portion 15b extends parallel in a manner offset with respect to the wall portion 14 and consequently also the central portion 16 of the side wall 11, 12. The transitions of the wall portions 15a, 15b are folding or bending lines.
In other words, a step-like or terrace-like configuration of the lower region of the end por-tions 15 is involved. In the region of the offset wall extent are the two openings 4 which are arranged in alignment with each other.
For its reinforcement, the otherwise perpendicular central portion 16 has a lower edge or wall portion 16a which extends in a bent manner obliquely with respect to the profile center plane M.

-11 -Figures 2 and 3 show that the horizontal wall 10 extends in the direction toward the end thereof obliquely in a downwardly bent manner, wherein a ramp-like chamfer 35 is produced at the end of the goods support 10A. The chamfer 35 is preferably inclined at an angle of 15 with respect to the horizontal wall 10 and is produced in such a manner that it is integrally connected or remains connected to the adjacent wall portions 14. There is thus, for example, no separating slot between the side edges of the chamfer 35 and the respective wall portion 14.
In order to engage the support 5, the cross-beam rear wall 8 of the cross-beam has two slots 21, 22 which are produced by means of punching and on which a locking projection 9 is formed in each case, wherein the two locking projections 9 are orientated toward each other. After reaching the locking state illustrated on the right in Figure 6, they engage in a positive-locking manner in the openings 4 and thus produce the positive-locking connection between the sup-port 5 and the cross-beam 2, 3.
Figure 6 shows beside each other the various stages when the support 5 is clip-fitted onto the respective cross-beam 2 or 3. In the first stage, as a result of the pressure applied from above to the support 5, the end portions 15 are deformed inward toward each other as soon as they move into abutment with the protrusion-like locking projections 9. In the central illustration of Figure 6, this process is already continued, the end portions 15 have moved further toward each other, wherein in this stage there is also still no positive-locking connection between the locking projection 9 and the opening 4 since the lower edge of the opening 4 still abuts in a resilient manner against the locking projection 9. Only in the third stage on the right in Figure 6 is there a covering of the opening 4 with the protrusion-like locking projection 9 so that the end portions 15 resiliently return to their original position again, wherein the locking projection 9 is locked in a positive-locking manner in the opening 4. In this assembly state, the end portions 15 are again completely free from bending forces so that the support 5 is also on the whole, after it has been engaged on the cross-beam, free from internal pretension ing.
In order to secure the respective support 5, the cross-beam rear wall 8 has the pairs of slots 21, 22 which extend from the cross-beam upper side 6 into the cross-beam rear wall 8.

In contrast, according to Figure 6, the lower edge 34, which ex-tends obliquely downward, of each side wall 11, 12 has no touching contact with the edge of the respective slot 21, 22.
According to Figure 4, the cross-beam 2 may have at the outer side thereof a cross-beam front side 50 which is connected in one piece to a wheel guide 51 in the form of a rail or is a compo-nent thereof. The rail comprises a horizontal portion 51 which is adjacent to the cross-beam front side 50, preferably supplemented by a vertical portion 52 which is adjacent thereto and which extends parallel with the cross-beam front side 50. The horizontal portion 51 provides the rolling face for a corresponding running wheel of a rack operating device or shuttle which is not illustrated. The vertical portion 52 and the vertical cross-beam front side 50 may form the lateral guide delimitations for the running wheel, wherein, however, a guide may also possibly be sufficient without the vertical portion 52.
Furthermore, the cross-beam upper side 6 has an oblique face 13 in the direction toward the cross-beam rear wall 8, wherein this oblique face 13 together with the chamfer 35 formed on the support 5 forms a flat V-shape in the engaged state of the support. This prevents any type of tilting of the goods during longitudinal displacement along the goods support 10A.
The slots 33 which at least partially separate the end portions 15, 17 from the long central portion 16 afford the advantage that during assembly at most some pressure has to be applied in the region of the recessed wall portions 15a, 15b, 15c, and no pressure to the two side walls 11, 12 overall. However, not even such a local pressure is required since, as a result of the specific configuration of the end portions 15, 17, a slight pressure from above on the horizontal wall 10 is already sufficient to engage the relevant end of the support 5 in a secure and per-manent manner with the respective cross-beam 2 or 3. The required assembly force is signifi-cantly reduced.
According to Figures 7 and 8, for the transport of the supports 5 to the construction location, it is advantageous for two supports to be inserted one into the other in each case. The supports 5 described here can be inserted one into the other in pairs, wherein the profile openings thereof are directed toward each other. However, the ramp-like chamfer 35 which is formed on one support prevents two supports 5 from being placed too tightly on each other. In order in this instance to again save a few millimeters of structural height with supports 5 which are laid one in the other in pairs, on the end portion 15 the lower edge 34 is configured in such a Date Recue/Date Received 2023-02-22

The rail comprises a horizontal portion 51 which is adjacent to the cross-beam front side 50, preferably supplemented by a vertical portion 52 which is adjacent thereto and which extends parallel with the cross-beam front side 50. The horizontal portion 51 provides the rolling face for a corresponding running wheel of a rack operating device or shuttle which is not illustrated. The vertical portion 52 and the vertical cross-beam front side 50 may form the lateral guide delimitations for the running wheel, wherein, however, a guide may also possibly be sufficient without the vertical portion 52.
Furthermore, the cross-beam upper side 6 has an oblique face 13 in the direction toward the cross-beam rear wall 8, wherein this oblique face 13 together with the chamfer 35 formed on the support 5 forms a flat V-shape in the engaged state of the support. This prevents any type of tilting of the goods during longitudinal displacement along the goods support 10A.
The slots 33 which at least partially separate the end portions 15, 17 from the long central portion 16 afford the advantage that during assembly at most some pressure has to be applied in the region of the recessed wall portions 15a, 15b, 15c, and no pressure to the two side walls 11, 12 overall. However, not even such a local pressure is required since, as a result of the specific configuration of the end portions 15, 17, a slight pressure from above on the horizontal wall 10 is already sufficient to engage the relevant end of the support 5 in a secure and per-manent manner with the respective cross-beam 2 or 3. The required assembly force is signifi-cantly reduced.
According to Figures 7 and 8, for the transport of the supports 5 to the construction location, it is advantageous for two supports to be inserted one into the other in each case. The supports 5 described here can be inserted one into the other in pairs, wherein the profile openings thereof are directed toward each other. However, the ramp-like chamfer 35 which is formed on one support prevents two supports 5 from being placed too tightly on each other. In order in this instance to again save a few millimeters of structural height with supports 5 which are laid one in the other in pairs, on the end portion 15 the lower edge 34 is configured in such a Date Recue/Date Received 2023-02-22
- 13 -manner that, starting from the vertical slot 33, it initially extends horizontally and then as an obliquely rising edge 37. The obliquely rising edge 37 corresponds virtually precisely to the chamfer 35 on the other of the two supports 5.
Figure 9 shows a variant of the support 5, in which the upper side of the support 5 in addition to the horizontal goods support 10A has an upwardly projecting edge 80 which extends along the goods support 10A over the entire length of the support. As a result of the edge 80, the goods which are supported on the goods support 10A are prevented from being able to slide laterally. This structural type of the support 5 is also used in pairs, wherein the edge 80 is located on the left on one support of the support pair and on the right on the other support of the support pair. The clip-fitting of this support 5 is carried out in the same manner as described above in relation to the other embodiments. In addition, in this embodiment, the chamfer 35 is also formed at the end of the goods support 10A.
If the support is provided for racks in which the storage and removal can be carried out from both sides, the securing of a push-through protection is advantageous, for example, in the center of the length of the goods support 10A. Figure 4 shows in the embodiment illustrated on the left such a push-through protection 86 for the securing of which to the horizontal wall 10 a securing structure 85 is formed, for example, an opening in the horizontal wall 10.
Figures 2, 4 and 5 show by way of example that the height of the side wall 11, 12 of the support 5 on the central portion 16 may have a greater height than on the front end portion 15 and/or on the rear end portion 17. In contrast, in Figure 3, these heights are substantially identical.
The greater height on the central portion 16 leads to an increased resistance force of the sup-port 5 so that relatively heavy load carriers can also be stored in the rack.
